Expected Hybrid Car Battery Lifespan

The good news is that hybrid vehicle manufacturers in the United States are legally required to provide a warranty on high-voltage hybrid battery packs for at least eight years or up to 100,000 miles. In addition, auto manufacturers in the U.S. are legally obliged to transfer the balance of any hybrid battery warranty to a new owner. Occasionally, high-voltage battery packs on hybrid cars can fail. Continue reading to learn what you can do to extend your hybrid car battery life on Hamilton, NJ roads and beyond.

Causes of Hybrid Car Battery Life Reduction or Failure

There are many possible reasons why hybrid car battery life might not be as long as expected. Individual cells or modules can fail in the battery, and the most common reasons are:

  • Poor electrical connections between cells or battery modules
  • Auto manufacturing defects in battery cells
  • Extreme high or low battery temperatures 
  • Manufacturing differences between cells
  • Mechanical damage to the battery during routine maintenance or service

How To Protect Your Hybrid Vehicle’s Battery Pack

Haldeman Lexus of Princeton does not recommend that you work on your own hybrid battery pack around Yardley, PA because they can be hazardous. Still, there is one significant thing you can do to protect your hybrid vehicle battery life that doesn’t include working on it yourself.

Don’t Ignore Warning Lights

The hybrid battery monitoring system has trouble codes and warning indicators that will show on your dashboard if it detects any issues, defects, malfunctions, or failures in the battery pack and its related systems. These kinds of issues may include:

  • Abnormal battery temperatures likely caused by problems with the dedicated computer-controlled battery cooling system
  • Imbalances between battery cells or battery modules – The failure of just one battery cell will likely degrade the performance of the entire battery pack
  • Abnormally high or low rates of charging

If a Hybrid Battery Dies, Can You Still Drive the Car?

Sometimes customers ask us, “If a hybrid battery dies, can you still drive the car?” The answer depends on which battery died. Fortunately, most hybrid cars have two batteries: the hybrid battery and a much smaller battery to operate the electronics in your vehicle. If the smaller battery dies, it’s not a problem. You can still drive it around Lawrenceville. However, if the main hybrid car battery is dead, do not attempt to drive the vehicle and make a service appointment at Haldeman Lexus of Princeton immediately.
